Not so much ruined, but one thing that was getting old was all the Kirk era characters showing up on the Enterprise years before Kirk took command on SNW. And yet the only "The Cage" era characters we see are Number One and Spock. This is not really a complaint about the actors playing the parts themselves. For the most part they have been fine.
I'd be fine with one or two other Kirk era characters showing up. But practically the entire command crew? I mean, hell, why not just add in Dr. McCoy already and complete the set? In the novels that took place in this era for instance other than Spock, Scotty was assigned to the Enterprise some years before Kirk took command as a junior engineer. There were some "The Cage" era characters still with the ship as well, and new characters.
